Ikebukuro Station (池袋駅) is a major railway station located in the Ikebukuro district of Toshima, Tokyo, Japan, shared by the East Japan Railway Company (JR East), Tokyo subway operator Tokyo Metro, and the two private railway operators Seibu Railway and Tobu Railway.

It primarily serves commuters from Saitama Prefecture and other residential areas northwest of the city center. It is the Tokyo terminal of the Seibu Ikebukuro Line and the Tobu Tojo Line.

Station layout
In Ikebukuro Station, there are two main entrances; the East Exit and the West Exit. There are a number of other secondary entrances such as the JR North Exit, the Metropolitan Exit, the various Seibu exits, and multiple subway exits.

The JR lines run north/south through the center. The Tobu platforms are to the northwest and the Seibu platforms are to the southeast. Both Tobu and Seibu operate department stores adjacent to their terminal stations. (Despite their names, "Seibu" (西武) starts with the kanji for "west" (西), but its platforms are on the eastern side of the station, while "Tōbu" (東武) starts with the character for "east" (東), but its platforms are on the western side of the station.)

The Marunouchi Line and Yurakucho Line run east/west two stories underground, while the Tokyo Metro Fukutoshin Line is four stories underground, to the west of the main station complex. The latter line runs south toward Shinjuku and Shibuya along Meiji-dori, and offers through services to Motomachi-Chūkagai Station in Yokohama via the Tokyu Toyoko Line and Minatomirai Line.

Tokyo Metro's underground mall "Echika" is also located inside the station.

Chest-high platform edge doors were introduced on the Yamanote Line platforms on 2 March 2013.

Platforms
The Tobu station has three terminating tracks served by platforms 1 to 5, arranged as shown in the diagram on the right.

Platforms 3 and 5 are normally used for disembarking passengers, although platform 5 is also used for passengers boarding the evening TJ Liner services, which require payment of a supplementary fare. From 14 June 2015, the departure melodies used when trains are about to depart from the station are to be changed to classical themes, with "Allegro" from "Divertimento in D major, K. 136" by Mozart used for platforms 1/2, "Menuetto" from "Eine kleine Nachtmusik" by Mozart used for platforms 3/4, and "Allegro ma non troppo" from the "Pastoral Symphony" by Beethoven used for TJ Liner services departing from platform 5.

Chest-high platform edge doors are scheduled to be added by the end of fiscal 2020. Platform doors protecting platform 1 are in use since 21 April 2018. It is planned to have platform doors protecting platforms 2 and 3 in operation from 2 March 2019.

History
The station was opened on 1 April 1903 by the Japanese Government Railways (JGR). The Tōjō Railway Line (present-day Tobu Tojo Line) station opened on 1 May 1914 with the opening of the 33.5 km line to Tanomosawa (田面沢駅) in Saitama Prefecture (located between the present stations of Kawagoeshi and Kasumigaseki). As the Tokyo terminus of the line was originally planned to be at Shimo-Itabashi, Ikebukuro Station is to this day marked by km post "-1.9" (the distance from Shimo-Itabashi Station where the "0 km" post for the line is located).

Tobu opened a department store adjoining its station on 29 May 1962. Around the same time, the Tobu station platforms were expanded with three tracks.

In March 1992, automatic ticket barriers were installed at the north exit of the Tobu Station, and in June of the same year, the Tobu Department Store was expanded with the addition of the Metropolitan Plaza annex located on the south side.

The station facilities of the Marunouchi and Yurakucho Lines were inherited by Tokyo Metro after the privatization of the Teito Rapid Transit Authority (TRTA) in 2004.

In June 2008, the Tobu station ticket barriers were color-coded into three "zones": North, Central, and South.

Chest-height platform edge doors were installed on the Tokyo Metro Yurakucho Line platforms in January 2011.

Station numbering was introduced to the JR platforms in 2016 with Ikebukuro being assigned station numbers JY13 for the Yamanote Line, JA12 for the Saikyo Line, and JS21 for the Shonan-Shinjuku Line.

On 1 March 2024, the departure melody on both Yamanote Line platforms was changed to the theme song of Bic Camera. The company has its head office and a major store building in the area.
